Abstract
An object of the present invention is to provide a digital VTR wherein, without increasing a transmission rate of an image memory and a data bus corrected thereto, a double error correction coding and decoding process can be achieved. In order to achieve the object, an input and output memory for storing an image data according to an input and an output formats, and a recording and reproducing memory for storing the image according to an image format are provided. To the input and output memory , via an input and output bus , an input and output circuits and is corrected. In data transmission between the input output memory and the recording and reproducing memory , a format conversion, and coding and decoding of an external code are performed. To the recording and reproducing memory , via recording and reproducing bus , inner coding and decoding circuits A and B are corrected.
